Tetra Whisper Bio-Bag Replacement Small Cartridges helps keep your filter functioning efficiently to remove odours and discolouration. Keeping your aquarium water clean is vital. Not only for the health of your fish, but for the clarity of the water. The filter in your aquarium is constantly removing decaying organic matter, chemicals, and excess food. Fish are constantly expelling waste as they swim, which is also cleaned up by the filter. This line of Cartridges are colour coded so it's easy to remember which size to purchase when it's time for a replacement. Simply rinse the bio bag under cold water to remove the carbon dust and then open the lid and insert it into the filter.
